Tire tread



FIG. 1 is a front elevational view of a tire tread showing my new design, it being understood that the tire pattern repeats circumferentially throughout the outer circumference;

FIG. 2 is a perspective view of one side of the tire tread shown in FIG. 1;

FIG. 3 is a fragmentary side elevational view of one side of the tire tread shown in FIG. 1; and,

FIG. 4 is a fragmentary side elevational view of the other side of the tire tread shown in FIG. 1.

In the drawings, the dark stippled surface shading represents the recessed portion of the tread grooves, having a depth as best shown along the top of FIG. 1. The broken line disclosure of the tire sidewall and inner bead is for illustrative purposes only and forms no part of the claimed design. 

The ornamental design for a tire tread, as shown and described.
